JDK 13 enters Rampdown Phase One

Rory O'Donnell

Hi All,

JDK 13 Early Access build 25 is now available at : - jdk.java.net/13/

  • Per the JDK 13 schedule [1], we are now in Rampdown Phase One.
    • For more details , see Mark Reinhold's email to jdk-dev mailing list [2] 
    • The overall feature set is frozen, no further JEPs will be targeted to this release.
  • Changes in this build 25 [4]

Request for feedback on JEP 353 integrated in b24

JEP 353: Reimplement the Legacy Socket API" has been integrated into jdk-13+24. It would be very useful if applications or libraries using java.net.Socket or java.net.ServerSocket APIs could test with this build and report any issues found. The JEP provides information on the system property that can be used to switch back to the old implementation and that may be useful to check for behavior differences between the old and new implementation. It would be very useful to get feedback via the OpenJDK net-dev mailing list, bugs via the usual channel.
